Deferred stop on thermal alarm
This function helps to prevent the drive stopping between two steps of the process if the drive or motor
overheats, by authorizing operation until the next stop. At the next stop, the drive is locked until the thermal
state falls back to a value, which undershoots the set threshold by 20%. Example: A trip threshold set at 80%
enables reactivation at 60%.
One thermal state threshold must be defined for the drive, and one thermal state threshold for the motor(s),
which will trip the deferred stop.

Thermal alarm stop function allow to set a custom alarm thermal level for the drive or the motor. When one of these levels is
reached, the drive trips in freewheel stop.

[Yes] (YES): Freewheel stop on drive or motor thermal alarm

If the assigned bit is at 0, there is no external fault.
If the assigned bit is at 1, there is an external fault.
Logic can be configured via [External fault config] (LEt) if a logic input has been assigned.

Parameter can be accessed if the external fault has been assigned to a logic input. It defines the positive or negative logic of
the input assigned to the detected fault.
LO
HIG
[Active low] (LO): Trip on falling edge (change from 1 to 0) of the assigned input
[Active high] (HIG): Trip on rising edge (change from 0 to 1) of the assigned input
